Abstract: TOWED VEHICLE ANTI-SWAY    BRAKE CONTROLLER     Abstract of the Disclosure A brake control system particularly suited for small trailers and the like wherein the angular velocity of each wheel in a selected pair of wheels is sensed and compared against each other to develop a control signal represent-ing the differential in angular velocity between the respective paired wheels.  In a skid control embodiment, while the brakes are being applied by the operator, the system automatically releases the brakes at both wheels in proportion to a velocity differential indicating an impending skid.  In the case of a trailer equipped with a sway control embodiment, the system automatically applies the brakes at both wheels in proportion to the velocity differential representing excessive trailer sway.  The respective skid control and sway control embodiments are useful alone or in a combined system.   i.

Title: Method and portable apparatus for monitoring the flow of liquid in an open channel
Inventor: MARTIG KENNETH W JR
IPC: G01F1/34
Filed: 1975-09-05
Granted: 1979-11-06
Abstract: Abstract of Disclosure A method and portable apparatus for monitoring liquid flow in an open sewer or water pipe or conduit.         The liquid depth is sensed by conducting a bubble fluid into the liquid from the exterior, bubbling it into the liquid, and sensing the static pressure of the overlying liquid thereagainst.  The sensed pressure is interpreted as depth of liquid and the flow determined from a known depth-to-flow relationship for the site being monitored.          The portable apparatus is provided with flexible collar-like means adapted to lie within the pipe or conduit and to be expanded to increased diameter, into contact with the inside wall thereof for frictional retention there-against and to be contracted to decreased diameter for removal therefrom.  The collar-like means carries sensor means including a bubble outlet for location in the vicin-ity of the flow bed or invert of the pipe or conduit and carries a bubble fluid conductor from the exterior thereto configured to lie closely adjacent the inside wall to mini-mize interference with the flow of liquid.

Abstract: COMPACT CORONA CHARGING DEVICE     ABSTRACT OF THE DISCLOSURE         A corona discharge device including a corona dis-charge electrode in contact or closely spaced from a conductive shield electrode, the discharge electrode comprising a con-ductive wire coated with a relatively thick dielectric material so as to prevent the flow of conduction current therethrough.  When the electrode is spaced from the shield, it is supported along its length on a dielectric surface and when it is in contact with the shield, the shield itself may provide the lengthwise support for the wire, or the support may alternatively be provided by a dielectric substrate on which the shield is carried.  The delivery of charge to the photoconductive surface is accomplished by means of electric field separation of charges produced by the discharge electrode.  These charges are produced by an alternating voltage applied to the discharge electrode. The flow of charge to the surface to be charged is regulated by means of a d.c. voltage bias applied to the shield electrode.

Abstract: Abstract of the Disclosure A balanced high pressure rising stem gate valve has lubricated metal-to-metal seal means between the bonnet part of the valve body and the valve actuating stem and between the chamber part of the valve body and the balancing stem.  Each seal means includes plural, e.g. three dished elastic metal ring gaskets with a high temperature resistant and chemical resistant ring of solid lubricant, e.g. tetrafluorethylene or graphite between each adjacent pair of metal gaskets.  Each metal gasket is softer than the stem and is of rectangular cross-section-and the edge at the inner periphery on the concave side is rounded.  Each seal means is disposed in an annular pocket in the adjacent part of the valve body extending around the stem.  Each-pocket is closed by an annular plug screwed into the pocket far enough  to flatten out the dished metal rings sufficiently for the inner and outer peripheries of each ring to engage the stem and pocket respectively with enough  pressure to cause plastic deformation of the inner peripheral edge on the concave side and the outer peripheral edge on the convex side, and to deform the elastic solid lubricant rings into engagement with the stem and pocket, and to prevent movement of the seal relative to the pocket when the valve is in use despite variations in the temperature of the valve and the pressure of the fluid therein and thereabout.  The valve stem sealing arrangement may also be em-ployed for packing off lock screws and in other situations wherein relatively movable parts are to be sealed both during and after relative motion.
